Guidance on Safe Use
Administrative data
First-aid measures
INHALATION
Use a chemicals protection suit. Avoid inhalation of vapors. Remove victim from contaminated atmosphere. Avoid contact with skin and eyes. Promptly remove non-impervious clothing that becomes wet or contaminated. Emergency shower and facilities for eye rinsing shall be available.
SKIN CONTACT
Rinse immediately with plenty of water. Promptly remove non-impervious clothing that becomes wet or contaminated.
Immediately rinse with water for several minutes. Do not try to neutralize. Get medical attention if any discomfort
continues.
EYE CONTACT
Rinse immediately with plenty of water. Remove any contact lenses and continue rinsing with water for at least 15
minutes (keep the eyelids open). Get medical attention immediately. Continue to rinse.
INGESTION
DO NOT INDUCE VOMITING! Rinse nose and mouth with water. Immediately give a couple of glasses of water or milk,
provided the victim is fully conscious. Never give anything by mouth to an unconscious person.
Fire-fighting measures
EXTINGUISHING MEDIA
Can be extinguished with dry sand, powder or carbon dioxide. Use extinguishing media appropriate for surrounding fire.
IMPROPER EXTINGUISHING MEDIA
Do not use a direct water jet that could spread the fire.
FIRE AND EXPLOSION HAZARDS
Non-flammable. When heated, sulfur dioxide vapour will evolve.
PROTECTIVE EQUIPMENT FOR FIRE FIGHTERS
General: Evacuate all personnel, use protective equipment for fire fighting. Use a portable breathing apparatus when
the product is involved in a fire.
OTHER INFORMATION
Containers close to fire should be removed or cooled with water. Persons without protective equipment and clothing
restricted from hazard area.
Accidental release measures
PERSONAL PRECAUTIONS
Wear necessary protective equipment. Evacuate the area.
SAFETY ACTIONS TO PROTECT EXTERNAL ENVIRONMENT
Prevent dispersion through damming with sand, earth or other suitable material. Prevent discharge into the sewage
system or the immediate environment (potential aquatic toxicity).
METHODS FOR CLEANING UP
Stop leak if possible without risk. Pump up liquid spillage with explosion-proof pump or hand pump, or use suitable
absorbent material. Minor spillage should be wiped away or flushed away with water. Large quantities should be
collected for treatment (neutralisation, combustion) in accordance with the local regulations.
OTHER INFORMATION
Inform Authorities if large amounts are involved.
Handling and storage
STORAGE
Storage in well-designed closed tanks. Storage plant must present a sufficient ventilation.
Avoid proximity with compatible chemicals and ignition source
HANDLING PRECAUTIONS
The product is corrosive.
HANDLING ADVICE
Use a chemicals protection suit. Avoid inhalation of vapours. Avoid contact with skin and eyes. Promptly remove nonimpervious
clothing that becomes wet or contaminated. Emergency shower and facilities for eye rinsing shall be
available.

Exposure controls / personal protection
EXPOSURE CONTROL
Storage substance in well-designed closed. Storage tank with in particular appropriate devices for vents to avoid vapor exposure. Provide good ventilation. Emergency shower and facilities for eye rinsing shall be available. Good working hygiene must
always be observed when handling product. Promptly remove any clothing that becomes wet or contaminated. Use
appropriate skin cream to prevent drying of skin.
RESPIRATORY PROTECTION
In case of insufficient ventilation, wear suitable respiratory equipment.
EYE PROTECTION
Tight-fitting goggles and face mask if risk of splashes or direct contact.
HAND PROTECTION
Protective gloves (butyl rubber, fluorocarbon rubber). Protective gloves (polyethylene).
PROTECTIVE CLOTHING
Use protective clothing that is resistant to chemicals.
Exposure Guidelines (by INRS ND 1945-153-93 and ND 192-155-94)
VLE (France) : 5 ppm
VME (France) : 2 ppm
Stability and reactivity
STABILITY
Product is reactive.
MATERIALS TO AVOID
In an open container, ammoium thiosulfate, ammonium sulfate will be genrated and sulfur dioxide will be vented. Ammonium can be vented in case of addition of strong alkalis with heated conditions.
Strong oxidizers will reacts with reducive species. Strong alkalis will accelerate the evolution of ammonia with dispersion.
Strong acids will cause the release of sulfur dioxide, highly toxic gas.
Ammonium bisulfite is not compatible with copper, zinc or alloys like bronze, brass, galvanized metals.
